816 Quarterly Eeport of the Chemical Committee, December 1891. 
cake made from the inferior seed. Tlie purchaser, while accepting 
the allowance, pointed out the unsatisfactory nature of the reply of 
the crushers, and the uselessness of guarantees between contractors 
and sub-contractors, when neither party took any steps to ascertain 
whether the conditions of the guarantee were being fulfilled, or to 
see whether the cake sold to customers was really " pure " cake as 
stated to be. 
3. Mr. E. L. Peel, on behalf of Lord Hastings, Melton Constable, 
East Dereham, Norfolk, forwarded on November 2 a sample of 
linseed-cake, which, after analysis, was reported upon as fellows : — 
Moistuie 
Oil 
^ Albuminous compounds (flesh-forming matters) 
Mucilage, sugar, and digestible fibre 
Woody fibre (celluloso) ..... 
Mineral matter (ash) 
' ContainiDg nitrogen .... 
This is not a pure cake, but contains con.siderablo admixture of weed 
seeds and starchy impuiities. 
The price of the cake was 9/. .'5.s'. per Ion on rail. Tlie present 
transaction consisted of one ton only, but large quantities had been 
purchased from the firm before. Mr. Peel added that he believed 
the vendors were not the makers of the cake, but only acted as 
agents, and, being dissatisfied with the quality of it, he was anxious 
to have Dr. Voelcker's opinion cn it. 
The order was given for " 1 ton linseed-cake," but the descrip- 
tion on the invoice was " 1 ton Riga cakes." 
This case illustrates how necessary it is that purchasers should 
see that the invoices correspond with the orders they give.

(July 1891) of the Chemical Committee, and published on p'age 6.33 
of the Journal for Septendser 30, 1891, Messrs. R. and J. Hewetson,
